+# Scriberr Typography Design System (Nunito)
+
+## Purpose
+
+This document defines a centralized typography system for Scriberr so hierarchy is explicit, scanning is faster, and typography remains cohesive across transcript, notes, and product surfaces.
+
+## Foundation
+
+- Primary font family: `Nunito` from Google Fonts.
+- Loading strategy: static local `@font-face` files in `web/frontend/public/fonts/nunito`.
+- Imported static weights: `400`, `500`, `600`, `700`, with matching italics.
+- Do not use range-based variable font imports for the app shell; browser font inspectors may expose the variable font's named instance instead of the active CSS weight.
+- The app root uses shared weight tokens for `400`, `500`, `600`, and `700`.
+- Single UI family across headings, body, metadata, controls, and note surfaces.
+- Serif reading utility remains optional for long-form reading experiments only.
+
+## Hierarchy Principles
+
+- Use scale and spacing before decoration.
+- Keep heading contrast obvious: larger size + stronger weight + tighter line-height.
+- Keep body text highly legible: medium weight + comfortable line-height.
+- Keep metadata quieter: smaller size + secondary/tertiary color.
+- Avoid one-off font sizes inside components unless product-critical.
+
+## Central Token Model
+
+All typography should consume shared CSS variables from `design-system.css`.
+
+Required token groups:
+
+- Family:
+  - `--scr-font-sans`
+- Weights:
+  - `--scr-font-weight-regular`
+  - `--scr-font-weight-medium`
+  - `--scr-font-weight-semibold`
+  - `--scr-font-weight-bold`
+- Sizes:
+  - `--scr-type-display-xl`
+  - `--scr-type-heading-lg`
+  - `--scr-type-heading-md`
+  - `--scr-type-body-lg`
+  - `--scr-type-body-md`
+  - `--scr-type-body-sm`
+  - `--scr-type-meta`
+  - `--scr-type-micro`
+- Leading:
+  - `--scr-line-tight`
+  - `--scr-line-base`
+  - `--scr-line-relaxed`
+
+## Recommended Mapping
+
+- Page/recording title: `display-xl` + `semibold` + `text-primary`.
+- Section heading: `heading-md` + `semibold` + `text-primary`.
+- Body/default: `body-md` + `medium` + `text-primary`.
+- Supporting copy: `body-sm` + `medium` + `text-secondary`.
+- Metadata/chips/timestamps: `meta` + `medium` + `text-secondary`.
+- Tiny labels/help/status: `micro` + `medium` + `text-tertiary`.
+
+## Notes Sidebar Typography Rules
+
+- Quote line should read as context: `heading-lg` on desktop, never bold-heavy.
+- Note bubble text should be compact and readable: `body-lg` with relaxed leading.
+- Reply placeholder/input should be one step quieter than note content.
+- Timestamp and count chips must stay compact and secondary.
+
+## Consistency Rules
+
+- New components must consume tokens; do not hardcode random font-size values.
+- Reuse existing semantic classes before adding new typography variants.
+- If a size is reused 3+ times, promote it to a token.
+- Typography adjustments should be made in token layer first, then component overrides.
+
+## Accessibility and Readability
+
+- Minimum body size for dense product surfaces: `0.875rem`.
+- Maintain clear contrast between primary and secondary text colors.
+- Avoid extreme font-weight jumps between adjacent levels.
+- Keep line lengths and vertical rhythm stable to prevent visual jitter.
